Sounds like Excel has either on add-in installed or some Auto_Open code.
Bearing in mind what you said about opening another document, I'd guess an
add-in is at fault. Go to Tools_addins and uncheck boxes one  at a time and
se what works.

I have not been able to find
anything like the add-ins you told me to look for under Tools. I have
gone through everything in my options and don't find  anything that
looks like it would be the problem. Any other ideas? I work on Excel
all the time but the most creative I have gotten was to link
information in one workbook  to another workbook, so, I am pretty
limited in my abilities. The sad part is that I am the most
proficient in my office. Any and all other suggestions accepted.

Just to clarify, did you go to the Add-ins dialog from the Tools menu and
find nothing checked there? Because if not (it's not clear from what you say
whether you got to the dialog or not) that would still be my first choice
for what's giving you a problem.

Did you get your problem  solved yet?

If not can you please indicate when getting this error message, what
options do you have to select on this error dialog box?
